Verstärkermodul mit LM3886 Für meine Bastelecke brauche ich einen Verstärker. Der sollte nicht hörbar rauschen oder brummen. Was das vorhandene Modul auf Basis LM3886 leider tut. Zumindest bei niedrieger einstellung des Lautstärkepotis, warum auch immer. Ich bekomme es nicht abge
Verstärkermodul mit LM3886 Für meine Bastelecke brauche ich einen Verstärker. Der sollte nicht hörbar rauschen oder brummen. Was das vorhandene Modul auf Basis LM3886 leider tut. Zumindest bei niedrieger einstellung des Lautstärkepotis, warum auch immer. Ich bekomme es nicht abgestellt und da ich sowieso mehr Kanäle brauche, dieses Projekt. Ziele: kein hörbares Rauschen oder Brummen. Leistung, ich habe einen 16v Traffo und der Kühlkörper ist vorhanden, das muss genügen.
